COAL-SPRINKLER FOR LOCOMOTIVES.

Application filed July 27, 1914..

To all whom it may concern:

Be it known that I, CARL EIBYE, a citizen of the United States, and aresident of East Boston, county of Suffolk, and State of Massachusetts,have invented an Improvement in Coal-Sprinklers for Locomotives, ofwhich the following description, in con nection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention relates to an improved system for sprinkling coal inlocomotive tenders and for other uses.

Heretofore it has been the practice to sprinkle the coal in the tenderof a locomotive with hot water from the boiler. Re cently laws have beenpassed which forbid this owing to frequent scaldings which haveoccurred. This makes it necessary to take the water directly from thetender and spray it on the coal. One of the principal objects of thisinvention is to provide an ejector system whereby the water may beconducted from the tender and be spread readily over the coal at a safetemperature.

The character of the invention may be best understood by reference tothe following description of an illustrative embodiment thereof shown inthe accompanying drawings, wherein:

Figure 1 is a side elevation of an illustrative system shown herein asembodying the invention;

Fig. 2 on an enlarged scale is a longitudinal section through an ejectorin the system;

Fig. 3 on an enlarged scale is a view partly in side elevation andpartly in section of a valve union in the system; and

Fig. 4 is a vertical section taken on line H of Fig. 3.

The illustrative system shown herein comprises a main pipe 1 leadingfrom the water tank in the tender to the main ejector for forcing thewater into the boiler of the locomotive. Tapped from this pipe is ashort branch pipe 3 connected with an ejector 5 (Fig. 2) of usualconstruction connected in turn by a pipe 6 with a union 7 having a shortpipe 9 for connection with a hose (not shown) for spraying the waterover the coal. The union is provided with a valve 11 (Fig. 4-) forcontrolling the delivery of the Water.

To force the water from the main pipe 1 up through the water deliverypipes a steam Specification of Letters Patent.

Serial No. 853,567.

pipe 18 is provided leading from the boiler and connected to said union.To control the steam the union is provided with a valve 15 (Fig. 4:).The union is connected by a pipe 18 with the ejector 5. To simulta-.neously control the opening of the steam and water valves they havestems 17 entered through packing boxes 19, 19, and fast to a bridgemember 21 secured to a screw 23 projecting upward therefrom and threadedinto a yoke 25 projecting up from and fast on said union and providedwith a frust-o pyramidal portion 27 to receive a hand wheel 29. Whenthis wheel is rotated it will lift the bridge member and with it thesteam and Water valves, thereby in one operation simultaneously openingthe steam and water pipes. On the occurrence of this event steam willpass from the boiler through the pipe 13, the union 7 and pipe 18 to andthrough the ejector, where it will pick up water from the main supplypipe. 1 and force the same up through the pipe (3 and the union andthence out through the hose to the coal.

The steam and water pipes connecting the ejector and union arenecessarily exposed where in cold weather the water therein is likely.to freeze. One of the objects of the invention aims to prevent this. Tothis end the union is provided with branch ducts 31 and 33 (Fig. 4)leading from the steam and water pipes to a common duct 35 having alateral port 37 delivering to the steam pipe above its valve. The commonduct may be closed by a screw cap 39 removable to facilitate cleaningthereof. Diametrically opposite the ducts leading from the steam andwater pipes are similar screw caps 41, L1 removable to facilitate thecleaning there of. To control the passage of steam through these ductsthere is provided a needle valve 4-3 (Fig. 3) projecting transverselyfrom the union and threaded into a packing nut 45 threaded to a bossprojecting from said union. The valve may be controlled by a handle 47.-When the needle valve is opened a small stream of steam will seep fromthe pipe 13 through the ducts into the water pipe 6 and steam pipe 18which are connected to the ejector. This will raise the temperature ofthe water therein sufficiently to prevent any possibility of freezingwith a very small expenditure of steam.

While the system is described herein for sprinkling the coal inlocomotive tender-sit may be used for other purposes if desired.

Having described one illustrative embodi ment of the invention Withoutlimiting the same thereto, What I claim as new and desire to secure byLetters Patent is:

1. A system comprising a water supply pipe adapted to lead from the tankof a locomotive tender, a delivery pipe, a steam supply pipe adapted tolead from the locomotive boiler, an ejector connected to said Watersupply pipe, a union separate from said ejector connected to said steamand delivery pipes, steam and water pipes connecting said union andejector, and valve means for controlling the discharge through saidunion.

2. r system comprising a Water supply pipe adapted to lead from the tankof a locomotive tender, a delivery pipe, a steam supply pipe adapted tolead from the locomotive boiler, an ejector connected to said Watersupply pipe, a union separate from said ejector connected to said steamand'delivery pipes, steam andwater pipes connecting said union andejector, valves in said union, and means for simultaneously openii'ig orclosing the same.

A system comprising a water supply pipe, a delivery pipe, a steam supplypipe, an ejector connected to said water supply pipe, a union connectedto said steam and delivery pipes, steam and water pipes conneetingsaidunion and ejector, valve means for controlling the discharge throughsaid union, and means in said union for admitting a small supply ofsteam to said pipes connecting said union and ejector, 7

t. A system comprising a Water supply pipe, and means for conductingWater therefrom including steam and Water pipes, an ejector, and valvemeans for controlling the supply of steamand water to the'ejector, andhaving means permitting the ad'i'nission of a sufficient amount of steaminto the system to prevent freezing therein.

5. A system comprising a Water supply pipe, a delivery pipe, an ejector,a union, steam and Water pipes connecting said union with said ejector,valve means in said union for controlling the passage of steam and Watertherethrough, 'a by-pass in said union around the steam valve, and avalve for said by-pass permitting the admission of a suflicient amountof steam in said steam pipe to prevent freezing therein.

6. A system comprising a Water supply pipe, a delivery pipe, an ejector,a union, pipes connecting said ejector and .union, valves in the latterfor controlling the passage of Water and steam through the union, ductsin said union connecting said steam and Water pipes, and valve means forcontrolling the passage through said ducts.

7. A system comprising a Water supply pipe, a delivery pipe, a steamsupply pipe, an ejector, a union interposed in said steam and Waterdelivery pipes, valve means for controlling the passage of steamandvvater through said union, and supplemental valve means in said unionpermitting the delivery of a small supply of steam into the system toprevent freezing thereof.

8. A system comprising a Water supply pipe 1, an ejector '5, a union 7,a steam pipe 18 and a Water pipe 6 connecting said ejector and union,valve means 15 in said union for-controlling the delivery of steam fromsaid union to said ejector, valve means 11 in. said unioncforcontrolling the delivery of the Water therefrom, and means including avalve 43' in said union for permitting steam to seep into said pipes 6and 18 to prevent the freezing of \vatertherein.

9. A valve fittingfor a system of the class described comprising a bodyhaving pas sages for conducting steam to and from said body, a valve forcontrolling the floivof. steam through said passages, passages forconducting water to and from said body, a valve for controlling the flowof Water through said passages, and a duct in said body connecting saidsteam and Water passages for permitting a seepage of steam from one tothe other.

10. A valve fitting for a system of the class described comprising abody having passages for conducting steam to and from said body, a valvefor cont-rolling the flow of steam through saidpassages, passages forconducting Water to and from said body, a valve for controlling the Howof Water through said passages, and ducts in said body for admitting aseepage of steam from one to the other of said steam passages and to oneof said Water passages.
